As mentioned, I think that you have to have the following in mind. Near
all plants (C3 or C4) have mycorrizhae associations, but C4 plants have a
fastest growth, wath is very important in Brasil (because erosion is a major
problem). Another point of view is that the type of "soil" you have on hand
is suscetible to erosion so, plants that would form a "carpet" on the soil
could be more interesting.
